ame() and lame() use named arguments (Xrow, Xcol,
Xdyad, symmetric, etc.) rather than a formula interface. The
summary() output renders a pseudo-formula for diagnostic display, but
it is not a valid R formula and cannot be passed back to a fitting function.
Usage
# S3 method for class 'ame'
formula(x, ...)
# S3 method for class 'lame'
formula(x, ...)
Arguments
- x
an ame or lame fit.
- ...
ignored.
Value
Never returns; raises an error.
